IMPROVEMENT lN MECHANICAL MOVEMENTS.

Specification forming part of Letters Patent No. 162,681, dated April27, 1875; application filed November 7, 1874.

To all whom it may concern Be it known that I, JOHN A. NEWELL, ofKalamazoo, in the county of Kalamazoo and State of Michigan, haveinvented a new Mechanieal Movement, of which the following is aspecification:

The nature of myinvention relates to a new and useful mechanicalmovement for converting rotary into reciprocatory motion, and has forits object to produce two vibrations of a bell-crank lever from onerevolution of the cranked driving-shaft, the movement being especiallyadapted to be used in connection with windmills and other slowmovingmotors, for producing a more rapid movement, as in churning.

Figure l is an elevation of the movement, showing the connecting-rod atthe highest point in its stroke. Fig. 2 is a similar view, showing theposition of the parts at the completion of the downstroke of theconnectingrod, the lower end of which is broken away to show the guide.

In the drawing, A represents a cranked driving-shaft, which may berotated by a windmill or other motor. B is a pitman connecting the crankwith the upper end of a plunger, 0, whichis thereby reciprocated in andthrough suitable guides on the face of the standard or frame-work of theapparatus. D is a connectin g-rod whose upper end is pivoted at a to theplunger 0, while its lower end is pivoted at b to one of a pair oftoggle-levers, E E, the inner ends of which are pivoted together, whilethe outer end of the lever E is pivoted to a curved bed-plate, F, andthe outer end of the lever E to the vertical shorter arm of abell-crank, G, pivoted at its angle to said bedplate. Thelonger arm ofthe bell-crank G has the churn-(lash or other object to be reciprocatedattached to it, and is depressed whenever the toggle levers areextended, or on the same plane, which is passed twice in eachreciprocation of the plunger; consequently the bell-crank will bevibrated twice in each revolution of the driving-shaft.

What I claim as my invention, and desire to secure by Letters Patent,is-

The herein-described mechanical movement, consisting of the pitman B,plunger 0,0011- necting-rod D, toggle-levers E E, bed-plate F, andbell-crank G, in combination with a cranked driving-shaft, substantiallyas described.
